Anton Kariagin and Stefan Gebert of Clariant discuss the benefits and commercial performance of the new low temperature shift (LTS) catalyst – ShiftMax 217 Plus. A case study demonstrates the benefits of this catalyst, providing ultra-low methanol formation resulting in increased ammonia production and/or energy savings.
Johnson Matthey's latest KATALCO™ 71-7F high temperature shift catalyst with its robust shape provides lower lifetime pressure drop.
Ammonia has been recognised as an advantageous hydrogen and energy carrier. This article focuses on the use of ammonia as fuel in steam reformers and ammonia crackers in order to reduce or completely eliminate direct CO2 emissions. Ammonia combustion knowledge is especially important for ammonia crackers with respect to the recycling of unconverted ammonia. Air Liquide is constructing an industrial scale pilot plant in Antwerp, planned to be operational in 2024, that will be used to demonstrate ammonia cracking and combustion in a process furnace with a multiple burner configuration.
Prices in the West are unlikely to garner much support moving into the latter stages of Q2. The May Tampa ammonia settlement was settled by Yara and Mosaic at $450/t c.fr, down $25/t on the $475/t c.fr agreed for April. With seasonal domestic demand in the US drawing to a close 2H April, many had anticipated that either a rollover or a slight decline would be agreed.
